The methodology and software for the use of broadband receivers to increase the sensitivity and informativeness of the URAN have been developed. The angular structure of several extragalactic objects was studied, the spectra of their components were obtained, and the radiation spectra of distant compact radio galaxies were determined. The peculiarities of the angular structure of extragalactic objects at decameter wavelengths and the possible reasons for its change with frequency are considered. The angular dimensions and location relative to the Sun of bursts of solar activity of III and IV types, as well as the diameter of the quiet Sun in the decameter band, were measured using short baseline interferometers. A close connection has been established between the high level of ionosphere scintillations and interplanetary ones during the passage of disturbances in the interplanetary medium caused by coronal mass ejections and streams of fast solar wind from coronal holes.
